API Installations
Wiring Instructions for a PAM-1 Relay
(Irrigation Control Interface Wiring)
• Connect the blue wire from the PAM-1 to IN- (below STANDBY)
on the API.
• Connect the orange wire from the PAM-1 to –REF on the API.
• Place a jumper wire from IN+ (below STANDBY) to +REF on the API.
• Connect the red wire from the PAM-1 to the MV/P (master valve/
pump) terminal on the irrigation controller.
• Connect the white wire from the PAM-1 to COM on the irrigation
controller.
• The yellow arrow dial on the API should face 2.
• When irrigation starts, you should see the Leak Defense System
control panel switch from Home or Away to Standby. When irrigation
stops, the Leak Defense System should go back to Home or Away.
NOTE:
This applies a 12-volt signal across the IN- and IN+ (below STANDBY ) terminals on the
API, while the irrigation system is running. You may be able to start irrigation manually to test
that this connection is functioning properly.
